# wget -c http://mirror.cc.columbia.edu/pub/software/apache/maven/maven-3/3.3.3/binaries/apache-maven-3.3.3-bin.tar.gz
# tar zxvf apache-maven-3.3.3-bin.tar.gz -C /usr/local/
# cd /usr/local/
# ln -s apache-maven-3.3.3 maven
# vi /etc/profile
export M2_HOME=/alidata/server/maven
export PATH=${M2_HOME}/bin:${PATH}

# wget -c https://github.com/medcl/elasticsearch-analysis-ik/archive/master.zip
# unzip master.zip
# cd elasticsearch-analysis-ik-master/
# cp -Rf config/* ik /usr/local/elasticsearch/config/
# mvn package
# /usr/local/elasticsearch/bin/plugin –install analysis-ik –url file:///alidata/download/elasticsearch-analysis-ik-master/target/releases/elasticsearch-analysis-ik-1.4.1.zip

3. 修改elasticsearch.yml
在该文件后面添加下面的内容

index:
analysis:
analyzer:
ik:
alias: [ik_analyzer]
type: org.elasticsearch.index.analysis.IkAnalyzerProvider
ik_max_word:
type: ik
use_smart: false
ik_smart:
type: ik
use_smart: true
index.analysis.analyzer.default.type: ik
|
4. 重新启动elasticsearch
|
1
|
/usr/local/elasticsearch/bin/elasticsearch –d
|
5. ik分词测试
创建一个索引，名为index
|
1
|
# curl -XPUT http://localhost:9200/index
|
为索引index创建mapping

# curl -XPOST http://localhost:9200/index/fulltext/_mapping -d’
{
“fulltext”: {
“_all”: {
“analyzer”: “ik”
},
“properties”: {
“content”: {
“type” : “string”,
“boost” : 8.0,
“term_vector” : “with_positions_offsets”,
“analyzer” : “ik”,
“include_in_all” : true
}
}
}
}‘

测试

# curl ‘http://localhost:9200/index/_analyze?analyzer=ik&pretty=true’ -d ‘
{
“text”:“www.ttlsa.com 教程太好了受益匪浅，望ttlsa越来越好”
}‘
